To all whom it may concern:

Be it known that I, JOSEPH Vi. How, a citizen of the United States, resiclin at Brooklyn. in the county of Kings and tate of New York, have invented new and useful Improvements in Paper-Tiihe iiiaking Machines, of which the following is a. specification. I

This invention relates i-o machinery for making paper tubes and like articles, and particularly to a "machine of this kind in which fihe complete opemtion of making and forming paper tubes and cutting them to finished. size, is automatically peri'omeci. Part of the original subjecbmatter of chis application is described and claimed in my divisional application, Serial No. 589,994, filed Septembei 23, 1922. 1

The principal object of my invention is to provide a machine which, when pm? in operation, automatically glues and Winds the paper strips into atube, emi. sch qzmccs the tube as formed. anricuis of? 'ihe tube in finisheci sections with sz'ziootli. ends I ready for as mailing tubes. 31'? ready to i eceive tops and bottoms to make paper cans 0r cartons. A further object is to pro video machiiie ingwhich the tube, as i is formed md advanced along a. mandrel. is roughly out by a revolviiig sew ospebie of traveling with the tube infio sections of approximafely any desired length. hhese sections being taken up by suitable convey ing mechanism and passed tocutting mechnnisi'n ,1 preferably embmiying disc knives which (tire bronghs into contact Wii'h the. cut of? portions of the tube, ancl cut these por tions to the desired finished lengths." em i'he! objects of my invention comprise the development 0:5. mechanism for conveying the cut off po rsione *fio the mechanism for cutting to finished size, the pwc-visicm of means for revolving the cut-off pfii i'flifi. and for bringing the cutting means into contact therewith, and for reinovil'ig the pieces out to finished size, as well mechanism to coordinate these functions anri cause them to occur suceesaively and. at such a rate as to concur with the scad at which the tube is formed upon the iflillbilfi.

My invention consists 'furicheir in construction, combination and errengement of parts herein described an claimed, and ii lusifirated in the accompanying (lmwings.

As soon as a portion is out of, it drops from the end of she guides, thus releas ing the lever 6 and permitting the saw 7 so be swung out of the way, and rei'nrncclio initial position, in the tisualinan nor. I

The out off poriions of tube as they olrop are received upon a rod 9 fixecl to the end. of the mandrel l, and are pushed along the rod 9 by the oil-coming tube advanoin from the mandrel The forward end of t is one off portion engages a conical-guiding 'iece l0 Whichserves to lift the portion oil the rod so shat it can be engaged by conveying mechanism comprising preferaily a nnmher of bolts 11 arranged to travel parallel to the-rod 9 and supporlzed upon wheels 12 arranged to be driven by suitable mechanism at a, speed such that when the tube portion is grasped by the belt. it is dragged rapidly forward at a rate much greater than the rate at which the tube-forming mechanism aclvances ihe tube.

This conveying mechanism carries the finbe portion forwarcl on to a roller 13 which is mounted, preferably with the use of ballbearings in line with end preferably direcfily upon the rocl 9.

The power for operating the conveying and" outting mechanism may be supplied from a suitable source, preferably the same that supplying the subs-forming mechanism through the belt 51, through abelt 14 arranged, to i'oiate a pulley 15 monn ied upon and adapted io rotate a shaft 16 from which power may be transmitted to a countershaft 1'? by means of a sprocket chain 68. and

I sprocket wheels '69 andYO mounted upon the shaft and conntershaft respectively; and a suii'abie framework is provided for supporting these mechanisms,

The mechanism for driving the belts l1 oi the conveyor is preferablyopera-tel from the connteirshaii' 17 through bevel Wheels 18 on the conntershaft, and 19 upon a verizicel shaft .90, which vertical shaft 26 carries bevel wheels 21 and 22" engaging bevel wheels and 24 respectively which are fixed to horizontal shafts 25, $56, carrying the wheels 12 which support the belts 11.

The mechanism for rotating the cut-off poriion of the tube after it has been forwarded by the conveying mechanism and advanced upon the roller 13, consists of'a pair oi friction-drive rollers 27 inounied in the frame of the machine, and preferably adjustable as to their position; in such a Way that the roller 13 normally rests upon and is snpporzed lay the fricl'ionwlrive rollar when ibe rod 9 is horizontal, the rocl 9 being oi consirierahle and somewhat flexible I prefer to ins ne the rolleis 27 ference less iihe iiaepo women n on adjustable arms 28 as Well shown in 1g.6, which may be clamped to rigid portions of the machine frame. and which permit adjiistment'o-f the rollers at bot-h emisso that they may be rendered exactly par allel with {he tube-receiving roller 13 when izhis roller has a portion of tube thereon is in contact with the friction-drive ri 27 The mechanism for rotating the imtion-clrive rollers preferably coznprises'oni is leys 29 fixed to the same she its as lhe roli ers and cxtenclingbeyonii the bearings so a to receive a turn of the driving helt ML. The driving. belt; 14 also passes over adjustable idler pulleys 30, the pins carrying whi. 1 may be ajusted to different posiiions aloha.

the slots 32 to regulate ibhe tension oi" iii belt.

In order to effect the feeding of igube po tions from the conveying mechanism on to the roller 13, as a cut oil tube portion do lirered from the conveying mechanism," ii; is; grasped by mechanism including a irioisioiii feed wheel 33 nionnteal immediately under a conicai guide portion which is fixed to the rod 9 and serves to gniole the tube upon the roller 13 This frictionfeed Wheelv 33 grasps the tube-porion shown in Fig. i, and makes the greater ereof a reVoln tion, dragging the tube poriion rapidly for" ward upon the roller 13 This vvlieei is of slightly greater diameter the (lietahce from its center up to the bottom line of the roller 13, when the roller is in nor-- m 1 position resting upon the friction-drive rollers 27. Consequently this friction feed wheel 33 serves to hoici the roller 13 in raisetl position out of contact with the frictiori-drive rollers 2'1 While the tube; portion is fed on, as shown in Figures anti 8. This friction ieed'wheel is provided was a flat portion 36 such that when this per-V tion is uppermost, iheroller 1.3 is allowed; to rest in conizaci: with the fricsion drive rollers. lhe diameter oi-ihe firiciion-feeil wheel such that the lengi h of the circumon is as least equalto the length of thoroughly onsfituhe yon fiione. I

The mechanism ior operatingthe iric-iion feed wheel is preferably arranged be driven from the couniershafi I? by means of bevei gears 37, 38, inonnteci respectively on the conntershait 17 ancl' upon the vertical shaft 39 additional bevel gearsfi, 41, being: inounteii respectively upon iih verth. cal shaft 39 and upon a horizontal-shaft 42 upon which the friction feed Wheel mounted. Supplementary feed wheels 56 may be provideiion veriic'al shafts 57 oar- 3 iicci in suitable brackets 60 and (lrivon'by hovel gears engsging bevel {rears 59 on ilic shaft 4:?"

The bevel gear 3? neon the shaft ii" is prei'erahly inarle wiiihj the teeth on only one i ms half thereof, so thnt, during one half revo- I lution of the shaft [7. the friction feed heel 33 is rotated. and (hiring the other half revolution ofthe shaft 17, the friction'fcedresting thereon, so that, the tube-portion may now be cutinto sections of the desired finished dimensions by thenpplicstioii of suitable knives. I

The mechanism for cutting the tube portions to finished sizes consists prefer ably of s plurality of disc knives 4C3 mounterl upon a shaft 44 hall'ifid"in arms 45 pivotally mounted on a. shaft and arronged to be brought into contact with the roller 13, or thrown out of contact therewith, by the operation of s cam 46 mounteti upon ths'countershsft 17. This coinis so upon the shaft 17 with respect to the teeth of he bevel gear 37 that the knives are brought into contact with the roller 13 durin that portion of the revolution offthe shsil 17 that the feed wheel 33 is-stationary and. with its flat portion uppermost, and the knives arentsken out of contact with the roller 13 before the feed wheel again commences to rotate. The connection between the cam and the arms 45' of the knife support comprises a,forkcd rod 47 carryingeroller 48 for cooperation with the cam surface, the forked portion coasting with the shaft. 17 to guide the rod, the upper end of the rod being pivotally connected with a cross bar til-connecting the arms 45 of the'kniie support so as to rock the support upon the shaft 50 to bring the linives -13 against the roller 13 as shown in Fig. 7.

In orzier to insure the quick return of the knives 43 to their position, as shown iii Fig. ti, out of contact with the roller when the rum permits the return to of'tlpositiona a spring 51 is preferably provided. In orderlhzit the knives may not be pressed i'ith injurious force against the rollers. a spring" 52 may be associated with the opera! in; rocl 47,

' extending upward from the cum 46 to the cross ar 49, the rod 1 7 preferably having; 1 siirlnljily arranged portion 55 normally held extendecl'bi' the spring52. The position of the shaft carrying the knives is pref eruhlv mode adjustable by means of the screws curried in the arms 45 arranged to move the slides 55 forming adjustable parts of the arms in which the knife-carrying shaft i4 is mounted, so as to render the knives parallel with the roller 13 and to permit thereto come just against the surface: thereof without cutting into the rollerend. f

injuring either the knives or the roller.-

-'.lhe operation of-the machine may be outlined as follows: I

The tube is formed in the ususl Way as in:

.dicsted in Fig. 2, being given a-rotuting and advancing movement. When the enfi reaches thelever, 6, the usual mechanism is tripped, bringmg the saw 7 llIiIORCtiOD to cut oi? a portion of the advancing tube, The

cut oli' portion tails, releasing the sawme'chanism and permitting it to repeat the cycle of operations outlined, and the cut oil portion is supported by the rod 9. The sclvancing tube pushes forward the cut off-portion, which passes beneath the lever 6, anti engages the conical guide 10 which lifts it off the rod 9 and permits it to be grasped by the belts 11. v

These belts drawthe tubeportion rapidly forward, making room for the succeeding tube, up to the end of the roller 13, when the feed wheel 33 comes into action. The belts 11, the feed meclnmismancl the cutting.

mechanism areroll operated from the'shsft 17, driven from the belt 14, which also ro' totes continuously the friction drive rollers 27. Consequently, the actions of these mechtwist is are all cooi'clinate. I

When the tube portion delivered by the i belts reaches the feed Wheel 33*, the Wheel is in position with its fiat portion uppermost the cam 46 is in a position such that thelrgnives are out of contact withth'e roller 13, the roller 13 with a tube portion cut to finished size is resting'upon the drive rollers 27, and. the teeth of the bevel gear 37 having teeth on one 'hslfofits face only are about to engage the teeth of the gear 38. As soon as these teeth 10 e'ngugeJthe frictionfeed wheel 33 is put in motion, grips the tube portion, raises the roller 13, and ad- I vances a tube portion thereon, ejecting the finished piece from the curl of the roller 13. When the tube portion is on the roller 13, the Wheel 33 completes a revolution, stoppingivith its flat portion uppermost as the rote,- on of the shaft '17 carries the teethof the WhEEEl 3? out of engagement with, those of the wheel 88, this position of the Wheel 33 permitting the roller 18-Withthe tube portion thereon, to rest upon the drive rollers 27 1 and be rotated thereby. Continued rotation of the shaft 17 brings the cam'46 into action; bringing the knives 43 against the roller 13.,-
